Overview
- Johnson disclosed his diagnosis on Good Morning America on Monday, saying he was diagnosed with sporadic ALS in 2025 and chose to speak publicly to help others and push for more research.
- He described a fast decline over about a year that cost him natural speech and forced him to communicate with a speech‑generating device that is triggered by his eye movements and uses recordings of his own voice.
- Johnson said his first symptom was weakness in his right hand, his original doctors warned that available medication might only extend life by months, and he responded by seeking care at a specialized ALS center.
- He is taking standard‑of‑care ALS medications and is enrolled in a clinical trial led by Dr. Merit Cudkowicz, whom he contacted after seeing prior ABC coverage of another patient’s treatment.
- The announcement drew public support from the Tennessee Titans, the New York Jets and many in the sports world, and it spotlights ALS as a progressive neurodegenerative disease with no cure and widely variable outcomes.
